Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to an auxiliary light structure and a fan light. Background Technology

[0002] In the field of lighting equipment, auxiliary lights, as important functional components, play a crucial role in improving the uniformity, layering, aesthetics, and functionality of the overall lighting environment by supplementing or assisting illumination. For example, patent CN222597539U utilizes a light-emitting strip within the outer frame groove to illuminate the ceiling from the back, solving the problem of dim ceilings caused by traditional ceiling lights that only illuminate downwards. Patent CN222230377U employs a ring-shaped light-emitting surface with tilted light emission to simulate the oblique effect of sunlight, enriching the layering of the lighting effect. Patent CN222392764U features auxiliary light components corresponding to surface light sources, projecting light to display the shape of decorative components, enhancing the decorative aspect of the lighting fixture. The fan light light guide component in CN211694592U allows more light emitted from the light source module to reach the illuminated area, avoiding light waste and thus improving the lighting efficiency of the fan light.

[0003] However, existing auxiliary light strips are generally installed using screws or adhesive backing. Screw installation requires a large installation space, resulting in a bulky and unsightly auxiliary light structure. While adhesive backing requires less installation space, it is difficult to position the light and can lead to misalignment and rework. Utility Model Content

[0004] In view of this, the present invention provides an auxiliary light structure and a fan light, which uses a snap-fit ​​method to install the light strip of the auxiliary light, which can reduce the installation space of the light strip, making the auxiliary light structure thin and beautiful, while also improving installation efficiency and reducing installation costs.

[0005] This utility model is achieved through the following technical solution:

[0006] An auxiliary light structure includes a light guide, a light strip, and a mounting base;

[0007] One end of the mounting base is folded outward to form a groove, and the inner wall of the groove is provided with a protruding structure. The light strip is snapped between the protruding structure and the bottom of the groove, and the light guide is connected to the opening end of the groove.

[0008] Furthermore, the protruding structure comprises several claws, each claw including a cantilever and a clamping head; one end of the cantilever is connected to the inner wall of the groove of the mounting base, and the other end is provided with the clamping head, which protrudes from the inner wall of the groove; when the light strip is installed, the cantilever can deform and spring back.

[0009] Furthermore, a U-shaped cut is provided on the inner wall of the groove, and the middle part of the cut is bent or stamped to form the claw.

[0010] Furthermore, the light strip includes a substrate and a plurality of LED beads arranged along the length of the substrate; the bottom of the clip is provided with a limiting surface, which is an inclined surface or an outwardly convex arc surface; the limiting surface abuts against the edge of the substrate, and along the horizontal direction close to the LED beads, the distance between the limiting surface and the substrate in the vertical direction increases.

[0011] Furthermore, the two sidewalls of the groove are designated as an outer ring and an inner ring, respectively, and the claw is disposed on the inner ring.

[0012] Furthermore, it also includes a pressure cap; one end of the light guide is connected to the pressure cap in a concave-convex fit, and the other end of the light guide is connected to the groove of the mounting base in a concave-convex fit, and the pressure cap is fixedly connected to the mounting base.

[0013] Furthermore, the inner ring of the mounting base is higher than the outer ring, the light guide is sleeved on the outer circumference of the outer ring, one end of the outer wall surface of the light guide is provided with a recessed mounting step I, the recessed mounting step abuts against the top surface of the outer ring; the other end of the light guide is provided with a recessed mounting step II, the recessed mounting step II abuts against the edge of the pressure cap.

[0014] Furthermore, the light guide is made of acrylic material and is formed using a baking and bending process.

[0015] Furthermore, the groove is located at the lower end of the mounting base, and the light strip faces upward to emit light.

[0016] A fan light, based on an auxiliary light structure, includes the auxiliary light structure and a fan light body;

[0017] An impeller is provided inside the main body of the fan light, and the auxiliary light structure overlaps at least partially with the impeller in the height direction;

[0018] The pressure cap is located at the upper end of the mounting base, is frustum-shaped, and tapers from bottom to top.

[0019] Beneficial effects:

[0020] (1) This utility model provides an auxiliary light structure that allows the light strip to be snapped into the groove of the mounting base, eliminating the need to reserve installation space on the light strip. This makes the auxiliary light structure thin and beautiful, and eliminates the need for other connecting parts, making it easy to install the light strip and reducing installation costs.

[0021] (2) The limiting surface of this utility model is an inclined surface or an outwardly convex arc surface. Along the horizontal direction close to the lamp bead, the distance between the limiting surface and the substrate in the vertical direction becomes larger and larger. The structure of the limiting surface can effectively prevent the claw from contacting the conductor.

[0022] (3) This utility model utilizes the local formation of claws on the inner wall of the groove, without the need to add other parts, which can further reduce the installation space and reduce the thickness of the auxiliary light structure.

[0023] (4) This utility model only sets claws on the inner ring of the groove. The limiting surface of the claws is a bevel or an outwardly convex arc surface, which generates downward and outward components of force on the substrate of the light strip. The downward component of force can limit the substrate of the light strip to the bottom of the groove, and the outward component of force can bring the substrate of the light strip close to the outer ring of the groove. Combined with the light guide above the light strip to limit the deformation of the light strip, the stability of the light strip installation is ensured. In addition, the claws set on the inner ring can also ensure the simple and beautiful appearance of the auxiliary light structure.

[0024] (5) This utility model connects the light guide with the pressure cap through a convex-concave fit, and connects the light guide with the mounting base through a convex-concave fit, which can directly limit the position of the light guide without further fixing, making installation simple.

[0025] (6) This utility model only requires two contact surfaces to complete the light guide component positioning, without the need for other connecting parts, and does not affect the light transmission; and the recessed mounting step II and the limiting position of the pressure cover are located on the inner wall of the light guide component, which does not affect the light guiding of the light guide component, making the light-emitting surface of the light guide component larger, which is conducive to improving the thinness of the auxiliary light lamp structure.

[0026] (7) The light guide of this utility model is formed by baking and bending process. In the field of lighting, baking and bending process is often used for metal materials. Applying baking and bending process to light guide can meet the diversity of light guide shape and size requirements, and the cost is lower than that of injection molding or casting.

[0027] (8) The groove of this utility model is located at the lower end of the mounting base, thereby fixing the light strip at the lower end of the light guide. Considering the effect of gravity, it is more stable and reliable than fixing the light strip at the top of the light guide. Moreover, the light strip emits light upwards, which improves the gentleness of the auxiliary light structure and is not dazzling.

[0028] (9) The auxiliary light structure of this utility model overlaps at least partially with the impeller in the height direction; the cover is frustum-shaped and tapers from bottom to top, which can visually reduce the thickness of the fan light and make the fan light look thinner and more beautiful.

Detailed Implementation

[0039] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0040] Example 1:

[0041] This embodiment provides an auxiliary light structure; see attached diagram. Figure 1-3 It includes a light guide 2, a light strip 3, and a mounting base 4;

[0042] One end of the mounting base 4 is folded outward to form a groove. The inner wall of the groove is provided with a raised structure. The light strip 3 is inserted between the raised structure and the bottom of the groove. The light guide 2 is connected to the opening end of the groove.

[0043] This embodiment provides an auxiliary light structure that allows the light strip to be snapped into the groove of the mounting base 4, eliminating the need to reserve installation space on the light strip. This makes the auxiliary light structure thin, beautiful, and easy to install the light strip.

[0044] See appendix Figure 4 The light strip 3 is a ring-shaped or arc-shaped light strip; when the auxiliary light structure is not ring-shaped, the light strip can also be other shapes, such as straight, triangular, square, elliptical, etc. The light strip can be LED light strip, OLED light strip, cold cathode fluorescent lamp (CCFL) light strip, halogen light strip, etc.

[0045] When the light strip is an arc-shaped light strip, there are two or more mounting slots at the bottom of the groove. The arc-shaped light strips are installed in the mounting slots one by one, and the mounting slots limit the installation of the arc-shaped light strips.

[0046] Furthermore, the groove is located at the lower end of the mounting base, thereby fixing the light strip 3 to the lower end of the light guide 2. Considering the effect of gravity, this is more stable and reliable than fixing the light strip 3 to the top of the light guide 2.

[0047] Let the two sidewalls of the groove be the outer ring 44 and the inner ring 41 respectively. The protruding structure can be set on the outer ring 44 alone, or on the inner ring 41 alone, or on both the outer ring 44 and the inner ring 41 at the same time.

[0048] See appendix Figure 5 and 6 The protruding structure consists of several claws 42, each claw 42 including a cantilever 421 and a locking head; one end of the cantilever 421 is connected to the inner wall of the groove of the mounting base 4, and the other end is provided with a locking head, which protrudes from the inner wall of the groove; when installing the light strip, the cantilever 421 can deform and spring back to install and limit the light strip 3;

[0049] The clip head includes a guide surface 422, an arc-shaped surface 423, and a limiting surface 424 connected in sequence; the guide surface 422 is connected to the cantilever 421 and forms an obtuse angle with the cantilever 421, so that when the light strip is pressed into the bottom of the groove, a horizontal inward force can be generated on the clip head; the arc-shaped surface is used for smooth transition to allow the light strip to be installed smoothly; the limiting surface 424 is located at the bottom of the clip head and is used to limit the light strip 3.

[0050] See appendix Figure 7 The light strip 3 includes a substrate 32 and a plurality of LED beads 31 arranged along the length of the substrate 32; the limiting surface 424 is a beveled or convex arc-shaped surface; the limiting surface 424 abuts against the edge of the substrate 32, and the distance between the limiting surface 424 and the substrate increases in the vertical direction along the horizontal direction closer to the LED beads. A conductor (such as copper foil) is provided on one side of the LED beads 31 to facilitate conductivity, and the structure of the limiting surface can effectively prevent the claws from contacting the conductor.

[0051] In addition, the card head can also be used for spherical cap structures, triangular prism structures, inclined plate structures, etc.

[0052] The claw 42 is integrally formed with the inner wall of the groove of the mounting base 4. Specifically, a U-shaped cut is provided on the inner wall of the groove, and the middle part of the cut is bent or stamped to form the claw 42. The claw is formed by utilizing a part of the inner ring 41, without the need to add other parts, which can further reduce the installation space.

[0053] The claw 42 is set on the inner ring 41 to ensure the aesthetic appearance of the auxiliary light structure.

[0054] In another specific embodiment, the protruding structure may also be a plurality of limiting protrusions 6 extending in the vertical direction. The end of the limiting protrusion 6 facing the bottom of the groove bends toward the lamp bead 31 and is provided with a slope in the vertical direction. When the lamp strip is inserted, it can be squeezed and deformed by the slope. After it is in place, the end of the limiting protrusion 6 locks the edge of the lamp strip and limits the lamp strip. In addition, the aforementioned locking head may also be provided at the end of the limiting protrusion 6 facing the bottom of the groove.

[0055] In another specific embodiment, the protrusion structure can also be a limiting protrusion extending in the horizontal direction. For the annular auxiliary light structure, the limiting protrusion is an annular protrusion or an arc-shaped protrusion. The inner diameter of the annular protrusion or the arc-shaped protrusion is smaller than the outer diameter of the light strip. When inserted, the light strip squeezes the protrusion to deform elastically, and the light strip is clamped by interference fit.

[0056] In another specific embodiment, the protruding structure can also be a dot matrix of protrusions, with several hemispherical protrusions processed on the inner wall to clamp the light strip through multi-point contact;

[0057] In another specific embodiment, the protruding structure may also be a plurality of hooks, each hook including a cantilever and a hook head. The cantilever is connected to the inner wall of the groove, and the cantilever is closer to the bottom of the groove than the hook head. The hook head may have a guide surface, an arc surface and a limiting surface, and the limiting surface is connected to the cantilever. When the light strip is inserted, the hook is pushed open, and when the light strip is in place, the hook head resets and hooks the light strip.

[0058] See appendix Figure 3 The groove bottom is also provided with a support portion 43 for supporting the light strip 3; see 6, the support portion includes a support surface 432 near the inner ring 41 and a support rib 431 near the outer ring 44, the surfaces of the support surface 432 and the support rib 431 are flush. The provision of the support rib 431 enhances the structural strength of the groove bottom, enabling the mounting base 4 to better withstand external forces, reducing the risk of deformation when subjected to external impact or compression, and protecting the light strip and the entire auxiliary light structure. The support portion helps maintain the stability of the groove shape and avoids deformation of the groove due to light strip installation or other external forces, which would affect the installation and performance of the light strip.

[0059] See appendix Figure 6 The mounting base 4 and the bottom of the claw 42 are provided with through holes 45, which can be used for wiring power supply of the light strip; in addition, conductive contacts can be integrated in the support to supply power to the light strip.

[0060] Working principle: The light strip 3 emits light when facing upwards, and the light is evenly emitted through the light guide 2.

[0061] Example 2:

[0062] This embodiment, based on Embodiment 1, provides an auxiliary light structure, see attached... Figure 1-3 It also includes a pressure cap 1; one end of the light guide 2 is connected to the pressure cap 1 in a concave-convex fit, and the other end of the light guide 2 is connected to the groove of the mounting base 4 in a concave-convex fit. The pressure cap 1 and the mounting base 4 are fixedly connected relative to each other.

[0063] The light guide 2 is connected to the cover 1 through a convex-concave fit, and the light guide 2 is connected to the mounting base 4 through a convex-concave fit. The light guide 2 can be directly limited without further fixing, making the installation simple.

[0064] The inner ring 41 of the mounting base 4 is higher than the outer ring 44. The light guide 2 is sleeved on the outer periphery of the outer ring 44. One end of the outer wall of the light guide 2 is provided with a recessed mounting step I, which abuts against the top surface of the outer ring 44. The other end of the inner wall of the light guide 2 is provided with a recessed mounting step II, which abuts against the edge of the pressure cover 1. Only two abutting surfaces are needed to complete the positioning of the light guide 2. No other connecting parts are required, and the light transmission is not affected. Moreover, the positioning point of the recessed mounting step II and the pressure cover 1 is located on the inner wall of the light guide 2, which does not affect the light guiding of the light guide 2, making the light-emitting surface of the light guide 2 larger.

[0065] The light guide 2 is made of acrylic material and is formed by a baking and bending process. Applying the baking and bending process to the light guide 2 can meet the diverse needs of the shape and size of the light guide 2, and the cost is lower than that of injection molding or casting.

[0066] In addition, the light guide 2 can also be made of one of PC (polycarbonate), PS (polystyrene) and glass. When one of acrylic, PC (polycarbonate) and PS (polystyrene) is used, the light guide 2 can be formed by injection molding or casting process; when one of acrylic, PC (polycarbonate) and glass is used, the light guide 2 can be formed by bending process.

[0067] Both the pressure cap 1 and the mounting base 4 can be made of plastic or metal.

[0068] In one specific embodiment, see Appendix Figure 3 and attached Figure 9 The pressure cover 1 is provided with a flange 12, and the bottom surface of the flange 12 abuts against the light guide 2. By providing the flange 12, the contact area between the pressure cover 1 and the light guide 2 can be increased, thereby improving the stability of the light guide 2 in positioning.

[0069] The pressure cap 1 is provided with a positioning rib 13, and the corresponding position of the inner ring 41 of the mounting base 4 is provided with a positioning groove 46. Through the cooperation of the positioning rib 13 and the positioning groove 46, the pressure cap 1 and the mounting base 4 can be quickly positioned and connected.

[0070] The top surface of the inner ring 41 of the mounting base 4 is higher than the lower surface of the flange 12, and the lower surface of the positioning rib 13 is flush with the lower surface of the flange 12.

[0071] See appendix Figure 2 The cover 1 is truncated cone-shaped and tapers from bottom to top, which visually reduces the height of the auxiliary light structure, making the lamp with the auxiliary light structure look thinner and more beautiful.

[0072] Example 3:

[0073] This embodiment is based on embodiment 2 and provides a fan light, see attached... Figure 1 and 2 , including the aforementioned auxiliary light structure and fan light body 5;

[0074] The main body 5 of the fan light is fixedly connected to the mounting base 4, and the auxiliary light structure is set on the periphery of the main body 5 of the fan light to achieve coordinated output of light effect and air volume.

[0075] The main body 5 of the fan light includes a housing, and the mounting base 4 of the auxiliary light structure is connected to the housing by fasteners or integrally formed.

[0076] An impeller is provided inside the main body 5 of the fan light, and the auxiliary light structure overlaps with the impeller at least partially in the height direction to visually reduce the thickness caused by the impeller.

[0077] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
